Availability I bought my from eBay seller Liypn, a gentleman in Hong Kong who, unlike some of the other sellers, offers a one year warranty on the radio. Your positions on each of the 12 bands on the dial face are remembered, unless you switch to memory mode, when they are effaced by presets.
Using Antenna SW antenna. The narrow IF setting is also helpful in pulling out a signal suffering under heavy noise. Apparently it accomplishes this quick sweep of a vast amount of spectrum through the use of a ee1103 comb-generating variablefrequency oscillator, mixing a large number of separate oscillator frequencies simultaneously. Many interesting emissions from modern office equipment were revealed but no bugs were found!
Alternatively, the unit can be operated by user-provided and externally-recharged NiMH or NiCd cells.

Spans of frequency bands may be swept from user-selectable widths of 0. Underneath the direct entry buttons are seven more buttons: The supplied telescoping whip enabled reception of two-way base stations from several miles away using the monitoring function.
Alternatively, the unit will lock onto a search-discovered frequency for monitoring. My replacement from a new lot so far shows no problems, though the faulty radio took about two months to begin acting up.
Spectrum analyzers can manually be tuned to various portions of the spectrum to visually display signals and some have audio recovery, but they tend to be large and expensive. Its VDC power jack makes it a natural for long-duration mobile operation, identifying nearby signals as they are approached or passed.

Typically, the Sweeper responds to signal levels above 20 microvolts in the MHz range, increasing to microvolts at 1 GHz, and 40 millivolts at the top end 2. It is not a selective, sensitive receiver that can distinguish between closely-spaced, weak or distant signals, nor does the display sweep or refresh quickly enough d1e103 show digital bursts, spread spectrum, frequency hopping, pulse, or single-signal waveforms.
As such, its display shows a single, narrow bar for a near-field signal, and the detector demodulates the strongest usually closest FM sources. A separate log memory bank can store up to first- or last-sweep-discovered frequencies with their own reports.
When near a station, you can use two fingers to turn the jog dial wheel slowly to find the exact frequency. Band Meter Band Conversion Build Quality I was impressed with the feel of the cabinet, aluminum front, and controls of the Up to 65, hits are recorded and reported by the memory which also stores frequency, signal strength, and a time and date stamp.
A huge plus was its scroll wheel which tunes in 1 kHz increments, and it was also fairly small. Table of Contents Add to my manuals Add. Still, manuual buttons are small, and your hand has to move around to find them, where the usual keypad format requires almost no movement and provides easy counting.
SSB is stable, and the fine tune dial feels smooth and solid. And, with the radio charging, pushing CHG changes the clock to the number of charging hours left. With the IF manua set to wide, I found the bleed-over ceased about 15 kHz up or down, at and Slide the battery lid.
When you reach the top or bottom of one of these bands, the needle snaps back to the opposite end of the band. My normal listening volume is between 8 and 12, 20 at the most to fill the room.
Press any button to stop auto scan tuning. Honestly, I was so glad to be getting a digital radio with a knob which tuned in 1 kHz steps, many of these other features were extras to me. Plug the adaptor into an V AC power outlet, connect the other side securely to DC Jack constantly displays, the unit is in charging process.
Many of these were intriguing and all had tuning knobs, but manusl of nanual read out to the last frequency digit.
Detailed specs of the and Degen line can be found at: The sound will be somewhat muffled and an increase in volume will be necessary, but the interfering signal will be drastically reduced or eliminated.
I was pleasantly surprised at the performance of these tiny, inexpensive units — pulling in African and European stations here on the U.
The backlight can be extinguished to extend battery life during high ambient lighting conditions. Don’t have an account? The signal-strength bar graph with its digital level readings is useful for antenna adjustments, bug detection, interference locating, signal-distance estimating and, with a directional antenna, hidden-transmitter hunting.
I was holding out for the ideal radio which would meet my list of desired features: The silver model especially has a nice finish and the bare aluminum face looks sharp. In the upper left corner are three buttons: Detected audio is clearly and loudly heard from the internal speaker, disconnected when an optional earphone is plugged into the 3.
